Abstract
A magnetic latchkey for an access-control lock with a series of magnets fastened to sliding pieces capable of being displaced by means of levers or extensions so that each magnet has three possible positions: north pole, south pole, or a point intermediate to both. This allows the magnet to be moved in front of the appropriate sensor of the lock, in such a way that when there is a particular combination of poles in the latchkey and the same combination of switches on the control panel, in touch with the position of the switches at the control panel will be identical to the positions of the levers of the latchkey. An alternative is for each magnet of the latchkey to have two sensors inside the lock.
Claims16
A magnetic latch arrangement comprising:
- a latchkey body;
- and
- a plurality of magnets movably contained in said latchkey body and each of said plurality of magnets movable into a plurality of positions with respect to said latchkey body,
- a lock having a recess means for receiving said latchkey body.
A magnetic latch arrangement comprising:
- a latchkey body;
- a magnet movably contained in said latchkey body and movable in to a plurality of positions with respect to said latchkey body;
- a lock having a recess means for receiving said latchkey body, said recess means being on a substantially flat planar outside surface of said lock, said lock having sensing means for sensing said position of said magnet;
- and
- a control panel means connected to said lock for receiving a key combination from said sensing means said key combination representing said position of said magnet, said control panel means also having a switch generating a control panel combination and said control panel means comparing said key combination with said control panel combination.
A magnetic latch arrangement comprising:
- a latchkey body;
- a magnet movably contained in said latchkey body;
- and
- mechanical movement means for moving said magnet into a plurality of positions with respect to said latchkey body,
- a lock having a recess means for receiving said latchkey body.
